Russia-Linked ‘GreyVibe’ Attackers Use AI to Supercharge Cyberattacks

GreyVibe is a Russia-linked hacking group that uses AI tools like ChatGPT and Google Gemini across all stages of attacks, from creating fake websites to building custom malware, targeting Ukrainian military and government entities since August 2025. Although the group appears less sophisticated than elite state actors (evidenced by design flaws in their AI-generated malware and casual naming conventions), they leverage AI to operate at a much higher capability level than their technical skill would normally allow. Researchers expect GreyVibe's AI expertise and attack complexity to continue increasing over time.
